Eduard Model Accessories has produced another fine set of photoetch parts to help complete your Supermarine Spitfire Mk. VIII. The set is for up-detailing the cockpit and you should need to add nothing more to make the cockpit area a highly accurate replica.
As an added bonus the parts in this set are prepainted and have an adhesive backing.
There are two frets, made from stainless steel and a clear film with four marked rectangles to replicate glass faces on instrument panels and gunsight reflectors.
